Overview

This 45-minute lesson, the 4th in an 8-lesson series on "Understanding Functional Foods," is designed for Year 13 students in New Zealand. The focus is on developing students’ ability to evaluate the credibility of nutritional information, identify "red flags" in nutritional messaging, and discern reliable from misleading health claims. This will build critical thinking and health literacy aligned with the New Zealand Curriculum’s principles, key competencies, and Health and Physical Education learning area.

Lesson Outline (45 minutes)

Time	Activity Description	Purpose / Links to Curriculum
0-5 min	Introduction & Warm-up Brief recap of previous lessons on functional foods. Introduce the concept of credibility in nutritional information. Pose the question: "How do we know if a nutritional claim is trustworthy?"	Activate prior knowledge; connect to Phase 5 focus of "Navigating pathways and developing agency" in Health and PE. Begin thinking competency development.
5-15 min	Group Brainstorm: Red Flags in Nutritional Messaging In small groups, students list potential red flags (e.g., exaggerated claims, lack of scientific evidence, testimonials, miracle cures) using prompts. Groups share with class. Teacher builds a composite list on whiteboard.	Engage students collaboratively; draw out prior assumptions; develop critical language and concepts for credible info (using language, symbols and texts competency). Builds critical analysis skill.
15-25 min	Guided Analysis of Real Examples Provide students with 3 varied examples of functional food advertisements or messages (real or simulated). In pairs, students examine each message and identify credible elements vs red flags.	Apply understanding in realistic contexts; scaffold critical analysis using evidence-based criteria aligned to Health curriculum aims. Emphasis on critical thinking and decision-making.
25-35 min	Class Discussion & Criteria Development Share analyses and as a class develop a checklist or criteria for spotting red flags in nutritional messaging. Include key questions like: Who is the source? What evidence backs this? Are there sweeping promises or scientific terms misused?	Collective knowledge building, deepening understanding. Encourage metacognition (thinking about thinking). Reinforce Key Competencies of thinking and using language/texts.
35-40 min	Individual Quick Activity Students evaluate a short nutritional claim passage with red flags embedded. Write a brief reflection: Which red flags are present? Would you trust this? Why or why not?	Individual synthesis to reinforce learning. Encourage self-management and reflection, building agency for lifelong health literacy.
40-45 min	Conclusion & Homework Brief Summarise key learnings. Set homework: Find an example of a nutritional claim (advert, social media post, product label) and identify if there are any red flags using class-developed criteria.	Consolidate learning. Extend learning beyond classroom in authentic contexts.

Teaching Strategies and Considerations

• Use flexible grouping to support varied learning styles and encourage peer support.
• Emphasise inclusive teaching, scaffolding criteria development for students who need it.
• Connect learning to students’ social and digital world experience with functional foods and health claims.
• Make explicit connections to the NZ Curriculum’s key competencies of thinking and using language, symbols, and texts.
• Encourage critical questioning attitudes essential for navigating today’s complex health and media environments.

This lesson supports students to become discerning consumers of health information, aligned to the New Zealand Curriculum’s vision of preparing young people to lead healthy, informed lives and participate actively and critically in society.

Teacher Reflection Notes

• Reflect on students’ ability to identify subtle red flags to improve future examples.
• Consider applying digital tools for interactive analysis if time permits or in follow-up lessons.
• Monitor engagement and encourage all voices during group discussions, ensuring respectful critical thinking.
